To all whom it may concern:

Be it known that 1, ROBERT P. FAIRBANKS,

a citizen of the United States residing at Pocatello, in the county ofannock and State of Idaho, have invented a new and usevide novel meanswhereby a film of liquid,

such as oil, may be presented to the inrushing air, novel means being provided whereby the film may be constantly renewed.

With the above and other objects in View which will appear as the description proceeds the invention resides in the combination and arrangement of arts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without depa'rtin from the spirit of; the invention.

In t e accompanying drawings Figure 1 shows in vertical longitudinal section, an air purifier constructed in accordance with the present invention, parts appearing in elevation;

Fig. 2 is a transverse section on the line 22 of Fig. 1, the line 11 in Fig. 2 designating the cutting plane upon which Fig. 1 is taken.

In carrying out the present invention there is provided a casing 1 which may be variously constructed as to size, shape and material, without jeopardizing the utllity of the invention. The casin 1 has been depicted as comprising a oX-like body 2 carrying a removable lid 3,-held in place by any suitable means indicated at 4. The ends of the body 2 of the casing are supplied with bearings 55. Apartition extends transversely of the casing 1 and divides the same into compartments 6 and 7. For a purpose to be set forth hereinafter, the partition may be described as including plates 8 and 9, the edges of which abut as shown at 23 in Specification of Letters Patent.

Application filed October 81, 1917. Serial No. 199,525.

Patented Dec. 311,

.Fig. 2. The plate 8 is secured to the body 2 of the casing 1 whereas the plate 9 is at- ,tached, as shown at 10, to the lid 3, the

construction being such that when the lid 3 is placed on the body 2, the plate 9 will enter the body and cooperate at 23 with the plate 8 to form a substantially air tight partition, as above described. Located on the lid 3 or elsewhere is an air inlet tube 11 wh1ch communicates with the compartment 6. The lid 3, referably, carries an air outlet 12, with which the compartment 7 communicates. The numeral 14 denotes the air intake of the carbureter of an internal engine, the air intake cooperating with the outlet 12 to form a conduit.

A shaft 15 is journaled for rotation in the bearings 5 on the body 2 of the casing 1, the numeral 16 denoting any suitable means whereby the shaft 15 may be rotated from a source of power. Fixed to the shaft 15 and mounted to rotate in thecompartmentfi 1s a drum which is a composite structure. The drum comprises an imperforate:

end wall 17, a spider 18 having'openings 19,

was. I

and a foraminous wall 20 assembled with the member 17 and with the spider 18. The spider 18 carries a flange 21, a portion of which is journaled in the plates 8 and 9 of the partition, the flange including a lip 24 which extends into the compartment 7 and overlaps the partition. It will now be understood that the partition is shown as comprising the separable plates 8 and 9, in order that the flange 21 may be placed, f0 rotation, in the partition. It .is contemplated that a liquid of some kind, preferably oil, indicated at 22, shall be laced in the body 2 of the casing 1. The i iquid being deep enough so that the drum dips into the liquid, as shown in Fig. 1.

In practical operation, air enters the casing 1*through the inlet 11 and, following the course indicated by the arrows, passes through the foraminous wall 20 of the drum or cylinder, the air passing through the openings 19 in the spider 18, into the commeans of the part 16. Ihe shaft 15, and the drum ordinarilv are rotated continuously. In this way, the film of oil is renewed continuously, the dust and other impurities which are collected from the air being Washed off as the wall 20 of the drum moves downwardly into the oil 22.

It is to be understood that the device forming the subject matter of this invention does not purport to supply fuel to the engine and is not to be confused with known structures in which a film of fuel is provided in order to make up the explosive mixture. The mechanism described and claimed is an air-purifier and is independent of the fuelsupplying means .for the ca-rbureter.

Having thus described the invention, what is claimed is l. A device of the class described, com prising a casing having a transverse internal partition defining compartments; a

shaft journaled in the ends of the casing; a drum on the shaft and located in one compartment, the drum comprising an imperforate end wall, and an end wall journaled in the partition and having an opening communicating with the other compartment; foraminous shell connecting the end walls;

an air inlet for one compartment; an air outlet for the other compartment; and

neans on the shaft and external to the casing for imparting rotation to the shaft from a prime mover.

2. A device of the class described comprising a casing including a body and a lid; a partition comprising a part carried by the body and a part carried by the lid, the parts of the partition having notches defining an opening in the partition, the partition dividing the casting into compartments; a foraminous drum disposed in one compartment and journaled in the opening of the partition, the drum being provided with a flange overlapping the partition about the opening and located in the other compartment; means for rotating the'drum; an air inlet for one compartment; and an air outlet for the other compartment.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

ROBERT P. FAIRBANKS.
